HEBI Robotics creates components that allow you to create custom robots quickly, and the HEBI APIs enable you to program these robots using your favorite programming language. The HEBI Mobile IO App is another component in this ecosystem; it integrates with HEBI APIs and tools to provide analog and digital inputs that can be used to control these robots. More information about HEBI robotic components can be found at http://hebi.us, and technical documentation for programming robots using these APIs is provided at http://docs.hebi.us. HEBI Mobile IO shows up as a network device that provides analog and digital "feedback" information, similar to the HEBI IO Board, as well as inertial measurements. This feedback can be accessed using the MATLAB, C, C++, and Python APIs for HEBI components, available for download at http://docs.hebi.us. You can also send commands from these APIs to alter the state and configuration of the HEBI Mobile IO app. Additionally, the camera is used in combination with Apple's ARKit technology to provide a full 6DOF pose estimate of the device as it is moved through the world. NOTE: This app is only useful in combination with HEBI APIs and tools, and does not provide utility as a standalone app.

Verdict
The clearest difference is update cadence: ntfy at fortnightly against HEBI Mobile I/O's every 3 months. ntfy also leads on ratings volume (483 vs 6). HEBI Mobile I/O's advantage is review sentiment (100% vs 79%) and rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.
